Advocate IIFormula.Firewall Query Foo references other queries, so it may not directly access a data source.
I am creating a lot of reports but they always hit the same API's on my app. To try to speed up the manual creation of reports I created a table called APISettings with a ProjectURL column. This means I only need to change a single field to reconnect all my queries to another URL.
This works great, but now I cannot merge two tables in PowerQuery as it gives me the error:

Doing some research in PowerPivot you could just set this setting to be ignored, but I cannot see how to do this in PowerBI?
Is there another way of registering my DataSource so that multiple queries all KNOW they are accessing the same one and can therefore allow merge etc?
Hi markive, the Firewall error is thrown when one evaluation is trying to access more than one data sources. Normally we partition your query automatically to split it into multiple evaluations across data sources, but there are some cases where this partitioning isn't smart enough. Can you post the query which has this problem?
Alternatively, you can turn this off in Options->Global->Security->Privacy Levels->Always Ignore (machine wide), or Options->File->Privacy (for the current file)

How can I do this in Visual Studio for AAS?
